Rathcroghan, about two miles from Tulsk, in the county Roscommon, is one of the most celebrated places in Irish history, legend, and song. It was there that Queen Mab, spelt Medb in old Irish, and Meave at present, had her palace, and it was there she was buried. That she was a real historic personage, and not a myth or a fairy, there can be no doubt at all, and that she was a very extraordinary woman cannot be doubted either. She was Queen of Connacht, and was cotemporary with Cleopatra; but if the Egyptian queen is mentioned in history she is forgotten in legend, while Mab has lived in legend for more than eighteen centuries. It is remarkable that the myths and legends about her should have been more prevalent during the sixteenth and seventeenth centuries in England than in Ireland. There are few legends about her in Ireland; she is simply an historic personage there, but in England she became a fairy. There is hardly a popular English writer of the two centuries referred to that has not said something about Queen Mab; and it is very probable that none of them knew that she was a reality in Irish history. Shakespeare, Spenser, Drayton, and other English writers contemporary with them, speak of her as a fairy, and even Shelley considers her a sprite; but she is rarely, if ever, mentioned as such by the Gaelic writers of any epoch. Why legends about Queen Mab, or, as we call her at present, Meave, should be so rare in Ireland is probably owing to the fact that she belongs to what is known as the Cuchulainn cycle of Irish history and legend. That cycle is almost forgotten by the people, and has been for many centuries. It has been eclipsed by the greater popularity of the Finn cycle, which is some centuries more recent. For the one legend existing in the most Gaelic-speaking parts of Ireland and Scotland about Cuchulainn or his cycle there are a score about Finn, Oisin, Caoilte, and others of their contemporaries. It may have been that the introduction of Christianity had much to do in stereotyping the legends of the Finn cycle in the memories of the masses, for Finn is said to have lived so long that he saw St Patrick, and held converse with him. One of the most remarkable literary productions in Irish, the "Dialogue of the Sages," consists of converse between the Saint and Finn, and others belonging to the same cycle.
